Hello, nlevine-firesmok. 

Thank you for reaching out to the Community. We can perform some troubleshooting steps to fix this.  

There are times that the browser is full of frequently-accessed page resources, thus accumulating and corrupts the browser cache causing the run time user interface to malfunction.

To start, access QuickBooks account using a private/incognito browser. You can use the shortcut keys below: 

• Google Chrome: Ctrl + Shift + N
• Internet Explorer: Ctrl + Shift + P
• Mozilla Firefox: Ctrl + Shift + P
• Safari: Command + Option + P  

If it works, we'll go back to your regular browser and clear the cache to get rid of the stored junk files. You can also use other supported browsers as an alternative and to roll out the possibility of a browser-related issue.     

Please see this article for more information: How do I switch companies? 

Let me know if you have other concerns that I can help you with. I'll be around. Stay safe!
